| 摘要 | The process of a gastropod (Tonna perdix) meeting its prey (Holothuria cinerascens) was recorded in a reef tidal pool in southern Taiwan. The sea cucumber reacted by taking in large quantities water to increase size. Diameter of body expanded from 3 cm to 7 cm and length shortened from 15 cm to 12 cm. The sea cucumber did not drift or move, but sank to the bottom and contracted its mouth, tube feet, and dorsal papilla. The small Tonna (3 cm in shell length) made no sign to engulf its prey, but approached and made contact with the anterior end of the sea cucumber for three minutes before moving away. The sea cucumber maintained its swollen state until the tide rose an hour later. This report confirms that the predator induced swelling behavior of H. cinerascens previously observed in the laboratory also occurs in the field. |
